SPECIFICATION formingpart of Letters Patent No. 763,645, dated June 28,1904.

Application filed December '7, 1903. Serial No. 184,171. (No model.)

T all whom, it may concern.-

Be it known that I, MARTYN ARNoLDUs VAN DERVVIELEN, director, a citizenof the N etherlands, residing at Rotterdam, in the Netherlands, haveinvented new and useful Improvements in Coin-Controlled Liquid-VendingApparatus, of which the following is a specification.

My invention relates to a coin-controlled apparatus for deliveringcertain quantities of liquidforinstance, water-in proportion to the oneor several coins inserted. The new apparatus is preferably arranged inconnection with a liquid-meter, and essentially comprises a valve-boxwith two valves, (the one for receiving liquid from the liquid-meter andthe other for discharging the liquid measured,) two levers for actuatingthe two valves, a locking-wheel, gearing connecting the liquid-meterwith the locking-wheel for driving the latter, an arm for disengagingthe locking-wheel from the gearing, a detent for looking or releasingthe locking-wheel, and a hand-slide arranged to move, by means of thecoin inserted, the two valve-actuating levers severally and thedisengaging locking-wheel through a I corresponding angle, whereuponthis wheel is again engaged. The whole construction of the new liquidvending apparatus will be hereinafter more particularly described, withreference to the accompanying drawings, in which Figure 1 is anelevation of the apparatus in a form of construction, the normalposition of the hand-slide being indicated by dotted lines. Fig. 2 is aplan of the same. Fig. 3 is a vertical longitudinal section through theapparatus without liquid-meter and registering device on the line A A inFig. 2, the handslide occupying its normal position. Fig. 4 is ahorizontal section through the same on the line B B in Fig. 1. Fig. 5 isa vertical crosssection through the valve-box on the line C C in Fig. 4.Fig. 6 is a vertical section similar to Fig. 3 in which the hand-slidehas been pushed inward a little. Fig. 7 is a horizontal section throughthe valve-box, the two valves being closed by the parts shown at Fig. 6.Fig. 8 is a vertical section similar to Fig. 3 in which the hand-slideis pushed inward through a farther distance. Fig. 9 is asimilar verticalsection in which the hand-slide is farther pushed inward and so muchthat the locking-wheel is disengaged from its gearing. Fig. 10 is ahorizontal section similar to Fig. 4 in which the parts occupy the samepositions as in Fig. 9. Fig. 11 is a vertical section similar to Fig. 3in whichthe hand-slide occupies its extreme positions when pushedinward; and Fig. 12 is a horizontal section similar to Fig. 4, showingthe relative positions of the parts for the same extreme position of thehand-slide as before.

Similar numerals indicate similar parts throughout the several views.

The coin-controlled apparatus is mounted on the base 1, of sheet metal,and is in connection with a known liquid-meter (or water-meter) 2. Theconstruction of the liquid-meter 2 is immaterial, it being onlyessential that the liquid-meter 2 be provided with a projecting shaft14, (see Fig. 3,) which is driven in any known manner by the liquidpassing through the meter while being measured. The liquid is assumed toenter themeter 2 through the inlet 42 and to leave the same through theoutlet 43. To the casing of the liquid-meter 2 a conveniently-shapedframe 4 is secured, which may be supported by a leg 3 shown. Thedriving-shaft 14 is tightened by a suitable stufiing-box 44 and isarranged to drive a vertical shaft 16 within the frame 4 by means of thebevel-wheels 15 and 17. The shaft 16 actuates a registering device 18 ofany known construction, so that the quantity of the liquid passedthrough the meter 2 will be shown on the dial of the said. device. Onthe lower end of the shaft 16 a pin- 7 ion 19 is fastened, which engagesa gear-wheel 20, secured on a vertical shaft 45. The latter is mountedto turn in a special frame 46, fastened on the bottom part of the frame4. Secured to the shaft is a second gear-wheel 21, which can engage witha gear-wheel 22, secured on a vertical shaft 23. On the frame 46 isfastened a guide 26 for the hand-slide 58 27. The guide 26 has avertical front wall to which the vertical coin-channel 28 is attached.

The whole apparatus may be assumed to be so inclosed in a suitablecasing (not shown) that the upper end of the coin-channel 28 terminatesin the top face of the casing andthat the knob 48 of the hand-slide 5827 always remains without the casing, while the inlet 42 of theliquid-meter 2 and the outlet 53 (which will be referred to later on)just project through suitable holes in the casing.

The guide 26 is provided with a boss 49, in which the shaft 23 turns. Onthis shaft 23 a locking-wheel 24 is fastened, which will be describedlater on. On the upper end of the shaft 23, between the top part of theframe 4 and a bearing 47, secured thereto, a gearwheel 37 is arranged sothat it is prevented from moving vertically, While the shaft 23 can beshifted longitudinally. It will be evident that on raising the shaft 23in a manner to be described hereinafter the gear-wheel 22 will bedisengaged from the gear-wheel 21, (see Fig. 9,) so that thelocking-wheel 24 can be turned as desired.

A valve-box 5, Fig. 5, is secured on the top plate of the frame 46 andprovided with two horizontal externally-threaded tubes 6 and 7, (seeFig. 4,) which thus can be adjusted longitudinally and secured by meansof counternuts 50 50. The one tube, 6, is connected with the outlet 43of the liquid-meter 2 by means of a tube 51 and a coupling 52. The othertube, 7, is cast in one piece with a nut 53, into which a dischargingtube or piece (not shown) is to be screwed.

The two tubes 6 and 7 are placed in two different vertical planesparallel to each other, and their internal ends serve as seats for thetwo valves 8 and 9. A horizontal shaft 10 at right angles to thehand-slide 58 27 and the two tubes 6 and 7 is mounted to turn in thevalvebox 5 and the front wall of the guide 26. (See Fig. 4.) On thisshaft 10 an arm 54 is fastened, to which the one valve,8, is so hingedthat it can readily apply itself to its seat on the shaft 10. On thefront end of the shaft 10 a lever 30 of the shape shown at Fig. 3 isfastened, by which the valve 8 is controlled. A sleeve 13 looselysurrounds the shaft 10 and passes through the cover of the valve-box 5,in which it is tightened by means of a stuffing-box 11. The external endof the sleeve 13 is made thick and equally tightened by anotherstufiing-box, 55. On the sleeve 13 within the valve-box 5 an arm 56 isfastened, to which the other valve, 9, is hinged, as shown at Fig. 5, sothat it applies itself to its seat on the sleeve 13. On the externalthick end of the sleeve 13 is fastened a bent lever 31 of the shape bestshown at Fig. 11 for controlling the valve 9. On the hub of. this lever31 a detent 32 (see Fig. 11) is fastened, which is arranged for engagingin the deep cut 25 of the locking-wheel 24, and thereby locking thelatter. The detent 32 is provided on the lower surface of its free endwith a ball 36, which is so held that it can freely roll on the topsurface of the locking-wheel 24 during the rotation of the latter,whereby the friction is reduced. On thedetent 32 a bent arm 33 (see Fig.9) is fastened, which is adapted to raise the locking-wheel 24, andthereby disengage it fromthe gearing. A spiral spring 35 is attached atthe one end to the top part of the frame 4 and at the other end to thedetent 32. This spring serves for pressing the detent 32 on thelocking-wheel 24, and on the former engaging in the cut 25 the spring 35also serves for pressing the valve 9 against its seat, and thus stoppingthe delivery of the liquid.

A fork-shaped slide 58 is mounted to move longitudinally in the guide 26and is rigidly connected with a rod 27 to form a hand-slide which can bepushed inward and drawn out by means of the knob 48. This slide 58 is somuch out out as to leave in its extreme position (shown at Fig. 11)suflicient space for the two levers 30 and 31. Near the left end theslide 58 is provided in its two arms with two vertical cuts 59 59, inwhich the coin 29, Figs. 6 and 8, inserted is allowed to movevertically. When drawn out, the hand-slide occupies such an extremeposition that its cuts 59 59 register with the opening in thecoinchannel 28, (see Fig. 4,) so that the coin 29 inserted falls intothese cuts 59 and is thereby held. The bottom of the guide 26 isprovided with three slots 60, 61, and 34. The one slot, 60, is so shapedas to allow the coin 29 to assume its lowest position (shown at Fig. 3)and to permit it to again rise on the hand-slide being pushed inwardfrom right to left, Fig. 6. The second slot, 61, is necessary forleaving space to the two levers 30 and 31. The third slot, 34, registerswith the cuts 59 when the hand-slide occupies its extreme position.(Shown at Fig. 11.) The slot 34 leads to a channel 62, Fig. 1, throughwhich the coin 29 can drop and fall into a convenient receptacle, (notshown,) guided by the two guides 63 63 on the base 1.

The locking-wheel 24 has several (here six) teeth, against either ofwhich the coin inserted is adapted to strike, so as to turn thelookingwheel through a corresponding angle. (See Fig. 10.) As thelocking-wheel 24 is prevented from turning when the detent 37 engages inits out 25, it will be evident that five coins at the utmost can beinserted one after the other and pushed against the lockingwheel 24 toturn it in the direction of the arrow. To prevent the locking-wheel 24from turning further, the gear-wheel 37 engages in a rack 38, providedwith a pointer 39, which latter projects through a slot of the scale 40.It is evident that on the pointer 39 pointing at 5 of the scale 40 itwill be stopped by the end of the slot and cannot move farther. Thescale 40 may also be made visible through a convenient opening or aglass plate in the casing inclosing the apparatus.

In order to enable the gear-wheel 22 to at locking-wheel. and therebybrings the latter into the correct position for dropping.

The apparatus described so far is operated as follows; Normallythehand-slide 58 27 oocupies its extreme position when drawn out and thedetent 32 engages in the cut of the locking-wheel24,-so that thedischarging- Valve 9 is pressed on its seat by the spiral spring 35,-and thereby stops the delivery. (See Figs. 3 to 5.) On inserting a coin29 in the channel 28-it will fall into the cuts 59 59 of the slide 58and occupy theposition shown at Fig.3. On pushing inward the hand-slideby means of the .knob 48 the coin 29 will soon the lever 30 and raisethe latter.

plied toits. seat. strikes against the second lever 31 and raises it, soas not only to detach thedischargingvalve 9 from its seat, but also tofirst disengage the detent 32 from the locking-wheel 24 (see Fig. 8) andthen to raise the latter by means of the arm 33 out of engagement withthe gearing. (See Fig. 9.) Now the coin 29 strikes against therespective tooth of the locking-wheel 24 and turns the latter in thedirection of the arrow in Fig. 10 through the distance of a pitch, whenthe slide 58 will attain its other extreme position and the coin 29drops through the slot 34 and the channel 62 into the receptacle. Thenthe two levers 30 and 31 are released, so taat the one, 30, returns intoits initial position and opens the receiving-valve 8, while the otherlever, 31, is checked by the locking-wheel 24 dropping into engagementwith the gearing, so that the discharging-valve 9 remains in its openedstate. Under the pressure of the liquid the meter 2 is now started, sothat liquid passes therefrom through the tubes 51 and 6, the valve-box5, and the tube 7 to the outlet. At the same time the driving-shaft 14is rotated to turn back'the locking-wheel 24 in the 'direction of thearrow in Fig. 12 and also to actuate the counter 18. 0f course duringthis time one or several further coins may be inserted to turn thelocking-wheel 24 forward if the quantity of liquid vended is to beincreased. In case five coins in all are inserted the locking-wheel 24will be so turned that its out 25 is brought into the position indicatedby the dotted lines in Fig. 12. The liquid will continue flowing outuntil the lockingwheel 24 returns into its initial position, when (SeeFig. 6.)"- In consequence of this-motion of the lever 30 with the shaft10 the receiving-valve 8 is ap- 5 At this moment the coin 29 the detent32, under the action of the spiral spring 35, will fall into the cut'25and stop the wheel-24. Thereby also the dischargingvalve 9 is againclosed.

It is evident that the quantity of the liquid delivered depends upon thenumber of coins inserted, as the locking-wheel 24 will take the moretime to return into its initial position the more coins are introduced.

The coin-controlled liquid-vending apparatus can be varied in manyrespects without deviating from the spirit'of my invention.
